ABSTRACT:
A method of converting a longitudinally elongated moulding rip having a portion containing a flaw such as a knot which is unacceptable in clear grade mouldings, into a substantially flawless premium length clear grade moulding, the rip having first and second flawless portions of substantially matching grain and a length less than a premium length, on either side of the portion containing the flaw, comprises the steps of cutting said rip transversely of its longitudinally elongated extent at both ends of the portion containing the flaw to provide smooth complementary first and second scarf joint faces on the ends of the first and second flawless portions respectively disposed adjacent the portion containing the flaw, removing the portion containing the flaw from between said first and second scarf joint faces, bonding said first and second scarf joint faces of said first and second flawless portions to one another to form a scarf joint connecting said first and second flawless portions to form a rip having a premium length, working the rip to produce a profiled moulding having a substantially flawless clear grade surface finish.
